The invention discloses a windscreen wiper driving device. The device includes a wiper motor, a driving rod connected to the wiper motor, a rotatably arranged crank in rotary connection with the driving rod, a first connecting rod and a second connecting rod that are connected to the crank, a first rocker rotatably connected to the first connecting rod and connected to a first windscreen wiper shaft, a second rocker rotatably connected to the second connecting rod and connected to a second windscreen wiper shaft, and an elastic element used for applying elastic acting force to the crank. According to the windscreen wiper driving device, through the arrangement of the elastic element, the instantaneous acceleration during reversing can be reduced, and the impact force generated in the wiperreversing process is reduced, therefore the abnormal reversing sound of a windscreen wiper is improved.

    本发明公开了一种雨刮器驱动装置,包括雨刮电机、与雨刮电机连接的驱动杆、可旋转设置且与驱动杆转动连接的曲柄、与曲柄连接的第一连杆和第二连杆、与第一连杆转动连接且与第一雨刮轴连接的第一摇杆、与第二连杆转动连接且与第二雨刮轴连接的第二摇杆以及用于对所述曲柄施加弹性作用力的弹性元件。本发明的雨刮器驱动装置,通过设置弹性元件,可以减少换向时的瞬时加速度,降低刮刷换向过程中会产生的冲击力大小,从而得以实现改善雨刮换向异响。
